"To all whom/it mdy con cemr T i Be it'known thatI, 'ELMER 1521mm? msianmmmam 1 citizen of the 'Unite'd stateg residin Puebloyin thecountyofPueblo and tate of Colorado, have" invented new and useful Improvements in MusiceLeaf Turners ,fqof

which thefollowingis a specification.

This invention relates to music leatturn ers, and the principal object of the nven-' tion is toprovide'a simple and efiici'ent mechanism whereby. withla single operating arm any. numberof sheets ofamusic may be I i "turned in succession from one positionto another- 1 Y "sheet turningar-m upon which themagnetis L mounted, and in which; the; stopping of the operating mechanism automatically acts to J Stillanother object of the invention isthe roduce a demagnetization of the magnet;

provisionfof a deviceofthischaracter, em-

ploying a single sheet turningarmfor mo e ing the sheet music from one'p'osition to another, in which the mechanism. is so :ar% ranged and controlled .thatthe sheet -turn-. I g I :its shouldered terminals '21 arranged to'jbe automatically raised to, disengage the sheet,

and? then automatically ,returned to its: ini

tial position for engagement with the sec -ond' sheet;

7 Further objects 'of' the ii nvention will appear as thefollowing specific description is read in connection with the accompany ng drawings, which form'a part of'th'i's appl1-.

The rodlOisheld adjusted position in the sleeve by a 'set. screw 12,- and the circuitof the magnet to the battery is indicated'by wires by the nu- I emerals' 13 and 14. i

The shaft aims as esses se mental f I gear, l5, which is arrangedto be engaged .by a similar gearlfisecured to'the upper f endof' the driving shaft 17.-" This driving! shaft is driven by an ordinaryspringamotorf 18, whichneeds no 'des'cri'ptiom'but islwound I up in the usual manner by the key '19, pro o I V jecting through the bottom ofithecasingl. 1 'Thegea-r 16 has -.-integrally formed therewith a segmental collar 20, which'hasione of engagedby a pines, pivotally mountedat' its lower end upon the switch lever 23 and normallyraisedinto operative position by a.

4 hav ng a finger]- In order that the magnet 11 and. its associate parts may be lifted from beneath the sheet after turning, the section 5 of the arm 4 is pivoted to the collar 6, as shown at 32,

1 so that when the outer end of the 4 rides over the inclinedportion 33 on the standard Bethe magnet will be lifted. It'will be more clearly understood hereinafter that prior to the lifting of the magnet the same will be deenergized' to. avoid lifting of the sheet, and that i mediately after lifting, the arm is returned to. initial position, inorder to engage another sheet. This'return ofthe larm 4f to initial position is accomplished by a spring 35 surrounding the shaft 3, and

connected at one end thereto and at the oppositejend to the casing.

Each music sheet 36 is supplied with a metallic disk 36' which is insulated from the sheet by adisk of mica or other suitable insulation. All these disks are so positioned upon the sheet that they will beywithin the range of adjustment of the magnet.

- The casing l-is preferably mounted upon the back of a sheet supporting board 39, and this board may carry, if desired, suitable music clamping mechanism, which will hold the music in its center, and, yet," permit pivoting of the sheet. The board may also carry the batteries,'if found to be desirable.

Inthe operation of the-device'the arms 5 and 6 and the rod 10 are adjusted so as to bring the magnet 11 in contact with a disk 36; onlthe first sheet of music. When it is desired toturn the sheet the lever 29 is "operated to bring the sweep lever into engageinent with' the terminal contact 27.

r 1 Simultaneously with the completion of the battery circuit or immediately succeeding the same, the pin 22 is withdrawn, from (m gagem'ent with the shoulder 21, against the tension of the spring 24. The spring motor 18 new acts to rotatethe shaft"17,thus causwith the pin, 22, butafter therelease 'of the switch arm from the conta-ct'27 thearm ,4

twill be brought'into engagement. with and ride upon the inclined. portion 33 on the standard 34, thus lifting the magnet from engagement with the disk after :itha's been deenergized, Also priorto the engagement of the shoulder 21 with the pin22 the toothed portion of the gear 16 will be disengaged from the toothed portion of the gear 15 and the spring 35 allowed to return the to mounted sheet turning arm, means normally tending to actuate the same for turning a sheet of music from one position to another, means for holding the'actuating means in inoperative position, means for connecting the arm witha sheetof' music, means for 'successivelyactuating the connecting means and releasing said holding means, and means for turning the sheet turning'arm'to normal position. i v
